How is your personal data collected?

  • Information we collect about you and your device. Each time you use the Service we automatically collect Usage Data. We collect this data using cookies and other similar technologies.

You can withdraw your consent at any time by disabling Location Data in your device settings.

  • Where you have consented before the processing.

Disclosures of your personal data

When you consent to providing us with your personal data, we will also ask you for your consent to share your personal data with the third parties set out below for the purposes set out in the table above:

  • Other businesses in the TDL group of business who assist us to provide the Service or to carry out any of the purposes explained in this policy.
  • Service providers acting as processors who provide IT services, analytics services and system administration services to us.
  • Professional advisers who need the data in order to provide advice to us, for example legal advisors.
  • Mixpanel, which is GDPR-compliant software that we use for analytics. It is part of the data collected when a user puts in a request of 'Send me a copy of my data'.
  • Third parties to whom we may choose to sell, transfer or merge parts of our business or our assets. Alternatively, we may seek to acquire other businesses or merge with them. If a change happens to our business, then the new owners may use your personal data in the same way as set out in this privacy policy.
  • Any third party that the law requires us to disclose the data to, or where we believe (acting in good faith) that the law requires us to disclose the data.

International transfers

Some of our external third parties are based outside the EEA so their processing of your personal data will involve a transfer of data outside the EEA.

Whenever we transfer your personal data out of the EEA, we ensure a similar degree of protection is afforded to it by ensuring at least one of the following safeguards is implemented:

  • We will only transfer your personal data to countries that have been deemed to provide an adequate level of protection for personal data by the European Commission. For further details, see European Commission: Adequacy of the protection of personal data in non-EU countries.
  • Where we use certain service providers, we may use specific contracts approved by the European Commission which give personal data the same protection it has in Europe. For further details, see European Commission: Model contracts for the transfer of personal data to third countries.
  • Where we use providers based in the US, we may transfer data to them if they are part of the Privacy Shield which requires them to provide similar protection to personal data shared between Europe and the US. For further details, see European Commission: EU-US Privacy Shield.

Please contact us if you want further information on the specific mechanism used by us when transferring your personal data out of the EEA.


Data security

Once we have received your information, we will use strict procedures and security features to try to prevent your personal data from being accidentally lost, used or accessed in an unauthorised way.

We have put in place procedures to deal with any suspected personal data breach and will notify you and any applicable regulator when we are legally required to do so.


Data retention

We will retain your personal data only for as long as is necessary for the purposes set out in this Privacy Policy.

In some circumstances you can ask us to delete your data: see below for further information.

In some circumstances we will anonymise your personal data (so that it can no longer be associated with you) for research or statistical purposes, in which case we may use this information indefinitely without further notice to you.


Your legal rights

Under certain circumstances you have the following rights under data protection laws in relation to your personal data.

You also have the right to ask us not to continue to process your personal data for marketing purposes.

You can exercise any of these rights at any time by contacting us at using the contact details at the start of this policy.


Your legal rights

You have the right to:

  • Request access to your personal data (commonly known as a "data subject access request"). This enables you to receive a copy of the personal data we hold about you and to check that we are lawfully processing it.
  • Request correction of the personal data that we hold about you. This enables you to have any incomplete or inaccurate data we hold about you corrected, though we may need to verify the accuracy of the new data you provide to us.
  • Request erasure of your personal data. This enables you to ask us to delete or remove personal data where there is no good reason for us continuing to process it. You also have the right to ask us to delete or remove your personal data where you have successfully exercised your right to object to processing (see below), where we may have processed your information unlawfully or where we are required to erase your personal data to comply with local law. Note, however, that we may not always be able to comply with your request of erasure for specific legal reasons which will be notified to you, if applicable, at the time of your request.
  • Object to processing of your personal data where we are relying on a legitimate interest (or those of a third party) and there is something about your particular situation which makes you want to object to processing on this ground as you feel it impacts on your fundamental rights and freedoms. You also have the right to object where we are processing your personal data for direct marketing purposes. In some cases, we may demonstrate that we have compelling legitimate grounds to process your information which override your rights and freedoms.
  • Request restriction of processing of your personal data. This enables you to ask us to suspend the processing of your personal data in the following scenarios:
    • (a) if you want us to establish the data's accuracy;
    • (b) where our use of the data is unlawful but you do not want us to erase it;
    • (c) where you need us to hold the data even if we no longer require it as you need it to establish,
      exercise or defend legal claims; or
    • (d) you have objected to our use of your data but we need to verify whether we have overriding
      legitimate grounds to use it.
  • Request the transfer of your personal data to you or to a third party. We will provide to you, or a third party you have chosen, your personal data in a structured, commonly used, machine-readable format. Note that this right only applies to automated information which you initially provided consent for us to use or where we used the information to perform a contract with you.
  • Withdraw consent at any time where we are relying on consent to process your personal data. However, this will not affect the lawfulness of any processing carried out before you withdraw your consent. If you withdraw your consent, we may not be able to provide certain products or services to you. We will advise you if this is the case at the time you withdraw your consent.
